Limited or No Connectivity Creteria

What checks does Windows XP/7 do to determine if a computer has limited or not connectivity? I realize Windows XP and Windows 7 perform different checks. I believe they ping a certain address and probably use DNS to some extent. But I was looking for the exact things they check to test connectivity.

Hello!

Check this out, I was actually wondering about this myself the other day!

Hi.

Let me tell you what about these superduper checks: On many (not all) of my networked computers, the nw-connectivity icons tell me "local network and internet access" - while these workstations are not connected to the internet. I don't know what this crappy check does, but it cannot reach files like http://www.msftncsi.com/ncsi.txt for sure. These computers are definitely offline (= not able to go online). So don't count on it.

McKnife,
Have you checked to see if NCSI is configured correctly on your machines? I personally have not had any obvious problems with the feature.

It is. But maybe I am wrong about what DNS request can be succesfully answered through our proxy. Will check tomorrow.

Ok, I was unaware that the DNS request (nslookup dns.msftncsi.com) will be served without internet access so that alone lets Windows Vista decide it has internet access.
